stockholders owning a majority of the issued and outstanding shares of the
capital stock of the Corporation entitled to vote at said meeting. At any
meeting of stockholders at which a quorum is not present, the holders of, or
proxies for, a majority of the stock which is represented at such meeting, shall
have power to adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present or represented. At

cast either in person or by proxy, appointed by an instrument in writing,
subscribed by such stockholder or by his duly authorized attorney, and filed
with the Secretary before being voted on, but no proxy shall be voted after
three (3) years from its date, unless said proxy provides for a longer period.
If the Certificate of Incorporation provides for more or less than one (1) vote
for any share of capital stock of the Corporation, on any matter, then any and
every reference in these By-Laws to a majority or other proportion of capital
stock shall refer to such majority or other proportion of the votes of such

Corporation, the vote of the holders of a majority of the capital stock entitled
to vote at such meeting and present in person or represented by proxy shall
decide any question brought before such meeting, unless the question is one upon
which, under any provision of the laws of the State of Delaware or of the
Certificate of Incorporation, a different vote is required in which case such
provision shall govern and control the decision of such question.

         Section 7.      Consent. Except as otherwise provided by the
Certificate of Incorporation, whenever the vote of the stockholders at a meeting
thereof is required or permitted to be taken in connection with any corporate
action by any provision of the laws of the State of Delaware or of the
Certificate of Incorporation, such corporate action may be taken without a
meeting, without prior notice and without a vote, if a consent in writing,
setting forth the action so taken, shall be signed by the holders of outstanding
capital stock of the Corporation having not less than the minimum number of
votes that would be necessary to authorize or take such action at a meeting at
which all shares entitled to vote thereon were present and voted. Prompt notice
of the taking of the corporate action without a meeting by less than unanimous
written consent shall be given to those stockholders who have not consented
thereto in writing.

         Section 8.      Judges. At every meeting of the stockholders of the
Corporation at which a vote by ballot is taken, the polls shall be opened and
closed, the proxies and ballots shall be received and taken in charge, and all
questions touching the

                                       6



qualifications of voters, the validity of proxies and the acceptance or
rejection of votes shall be decided by, two (2) judges. Said judges shall be
appointed by the Board of Directors before the meeting, or, if no such
appointment shall have been made, by the presiding officer of the meeting. If
for any reason any of the judges previously appointed shall fail to attend or
refuse or be unable to serve, judges in place of any so failing to attend, or
refusing or unable to serve, shall be appointed in like manner.

the annual meeting of the stockholders of the Corporation, except as provided in
Section 2 of this Article, to serve until the next annual meeting of
stockholders and until their respective successors are duly elected and have
qualified.

         In addition to the powers by these By-Laws expressly conferred upon
them, the Board may exercise all such powers of the Corporation as are not by
the laws of the State of Delaware, the Certificate of Incorporation or these
By-Laws required to be exercised or done by the stockholders.

reason other than the removal of a Director pursuant to Section 3 of this
Article, and any newly created Directorship resulting from any increase in the
authorized number of Directors, may be filled by a majority of the Directors
then in office or by a sole remaining Director. In the event that any vacancy in
the office of a Director occurs as a result of the removal of a Director
pursuant to Section 3 of this Article, or in the event that vacancies occur
contemporaneously in the offices of all of the Directors, such vacancy or
vacancies shall be filled by the stockholders of the Corporation at a meeting of
stockholders called for the purpose. Directors chosen or elected as aforesaid
shall hold office until the next annual meeting of stockholders and until their
respective successors are duly elected and have qualified.

hereinafter provided, for special meetings of the Board of Directors.

hours, or shall be sent to him at such place by facsimile transmission, courier,
telegraph, cable or wireless, or shall be delivered personally or by telephone,
at least twelve (12) hours, before the time fixed for the meeting. At any
meeting at which every Director shall be present or at which all Directors not
present shall waive notice in writing, any and all business may be transacted
even though no notice shall have been given.

         Section 8.      Quorum. At all meetings of the Board of Directors, the
presence of one-third or more of the Directors constituting the Board shall
constitute a quorum for the transaction of business. Except as may be otherwise

Incorporation or

                                       9



these By-Laws, the affirmative vote of a majority of the Directors present at
the time of such vote shall be the act of the Board of Directors if a quorum is
present. If a quorum shall not be present at any meeting of the Board of
Directors, the Directors present thereat may adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum
shall be present.

         Section 9.      Consent. Unless otherwise restricted by the Certificate
of Incorporation or these By-Laws, any action required or permitted to be taken
at any meeting of the Board of Directors may be taken without a meeting, if all

not receive any stated salary for their services, but, by resolution of the
Board, a fixed sum and expenses of attendance, if any, may be allowed for
attendance at each regular or special meeting of the Board; provided that
nothing herein contained shall be construed to preclude any Director from
serving the Corporation in any other capacity and receiving compensation
therefor.

         Section 1.      Certificates of Stock. The certificates for shares of
the stock of the Corporation shall be in such form, not inconsistent with the
Certificate of

                                       15



Incorporation, as shall be prepared or approved by the Board of Directors. Every
holder of stock in the Corporation shall be entitled to have a certificate
signed by, or in the name of the Corporation by, the President or a Vice
President, and by the Treasurer or an Assistant Treasurer or the Secretary or an
Assistant Secretary certifying the number of shares owned by him and the date of
issue; and no certificate shall be valid unless so signed. All certificates
shall be consecutively numbered and shall be entered in the books of the
Corporation as they are issued.

         Where a certificate is countersigned (1) by a transfer agent other than
the Corporation or its employee, or, (2) by a registrar other than the
Corporation or its employee, any other signature on the certificate may be
facsimile. In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased
to be such officer, transfer agent or registrar before such certificate is
issued, it may be issued by the Corporation with the same effect as if he were
such officer, transfer agent or registrar at the date of issue.

         All certificates surrendered to the Corporation shall be cancelled and,
except in the case of lost or destroyed certificates, no new certificates shall
be issued until the former certificates for the same number of shares of the
same class of stock shall have been surrendered and cancelled.

         Section 2.      Transfer of Stock. Upon surrender to the Corporation or
the transfer agent of the Corporation of a certificate for shares duly endorsed
or accompanied by proper evidence of succession, assignment or authority to
transfer,

                                       16



it shall be the duty of the Corporation to issue a new certificate to the person
entitled thereto, cancel the old certificate and record the transaction upon its
books.

                                  ARTICLE VIII

                             Registered Stockholders

         The Corporation shall be entitled to treat the holder of record of any
share or shares of stock as the holder in fact thereof and, accordingly, shall
not be bound to recognize any equitable or other claim to, or interest in, such
share or shares on the part of any other person, whether or not it shall have
express or other notice thereof, save as expressly provided by the laws of the
State of Delaware.

                                   ARTICLE IX

                                Lost Certificates

         Any person claiming a certificate of stock to be lost or destroyed,
shall make an affidavit or affirmation of the fact and advertise the same in
such manner as the Board of Directors may require, and the Board of Directors
may, in its discretion, require the owner of the lost or destroyed certificate,
or his legal representative, to give the Corporation a bond in a sum sufficient,
in the opinion of the Board of Directors, to indemnify the Corporation against
any claim that may be made against it on account of the alleged loss of any such
certificate. A new certificate of the same tenor and for the same number of
shares as the one alleged to be lost or destroyed may be issued without
requiring any bond when, in the judgment of the Directors, it is proper so to
do.

                                       17



                                    ARTICLE X

                              Fixing of Record Date

         In order that the Corporation may determine the stockholders entitled
to notice of or to vote at any meeting of stockholders or any adjournment
thereof, or to express consent to corporate action in writing without a meeting,
or to receive payment of any dividend or other distribution or allotment of any
